## Other investigations on N8608W (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB WPR11LA102](https://openairdocs.org/ntsb/WPR11LA102), Jan 20, 2011: Piper PA-28-235 (N8608W), San Luis Obispo, CA, substantial damage. Probable cause: The loss of engine power due to the fatigue fracture of one attachment bolt for the left idler gear shaft, which resulted from an insufficient preload on both attachment bolts.
